Yes, paper towels can create tiny, microscopic scratches (micro-scratches) on mirrors. This happens because they are made of wood pulp and can be abrasive. Over time, these faint abrasions build up, dulling the glass, shortening its lifespan, and leaving behind annoying lint.
Mirrors, windows, and glass also risk scratches when wiped with the abrasive material in paper towels, so you'll want to opt for a softer fabric when cleaning these surfaces.
Go for a thin, flat-weave microfiber cloth for best results
Your cleaning rag matters just as much as your solution. Avoid paper towels, and thick terry cloth, as they can leave behind particles on your mirror… thereby defeating the purpose of this exercise. A thin, flat-weave microfiber cloth is best.
The best way to clean a mirror without streaking is the two-towel method using a lint-free Microfiber Cleaning Cloth and a mixture of 1 part distilled water to 1 part white vinegar (or Sprayway Glass Cleaner).

Cleaning A Mirror? 4 Alternatives To Glass Cleaner You Can Use
Professional glass cleaners prioritize ammonia-free formulations that prevent streaks and protect window tints. Top-rated products for commercial facilities, automotive detailing, and architectural cleaning include highly concentrated soaps and ready-to-use sprays that safely cut through grime, smoke haze, and fingerprints.
Mirror Rot is caused by moisture penetrating between the layer of glass and the layer of metal. Once water vapour has wormed its way in, the metal that makes your mirror shiny begins to react and oxidize (rust), turning an ugly black.
Dawn as a substitute glass cleaner
One of the most effective ways to clean glass is dish soap – it's what professional window cleaners use when cleaning exterior windows. Dish soap can remove stuck-on dirt and cuts any hazy build-up. It also works well on cloudy mirrors.
Your mirror is likely streaky because of leftover residue. This usually happens when you use too much cleaning product, use a dirty or lint-producing cloth (like paper towels or cotton rags), or if you wipe the mirror in circles instead of straight lines.
The consensus is that paper towels are kind of the worst for cleaning mirrors. They shed so much lint and can be wasteful. Maker adds, “Rags are also not absorbent and leave streaks behind.” So what's the perfect product? According to both Maker and Pleshek, microfiber towels will guarantee spotless mirrors.
Top Mirror Cleaning Mistakes to Avoid
While white vinegar is an excellent natural cleaner, its acidity means it can damage certain surfaces, strip finishes, or cause rust. You should generally avoid using it on:

WD-40 doesn't actually repair scratches, but it is excellent at temporarily hiding very light surface marks and removing paint transfers (like when another car scrapes yours). It works by acting as a lubricant and temporarily filling in the scratch or dissolving the foreign paint.
The absolute best mirror cleaner is actually a flat-weave microfiber cloth and plain water. For tougher grime like hairspray or toothpaste, rubbing alcohol or a DIY mix of equal parts water and white vinegar works best. For a store-bought foam, Sprayway Glass Cleaner is highly rated for leaving no streaks.
Your reflection in a mirror is actually a reversed version of your face, meaning you've never fully seen yourself the way others do. Every time you look into a mirror, you're viewing a left-to-right flip, a version your brain has grown familiar with but one that isn't truly accurate.
Let it sit for 10-20 minutes. The vinegar will help loosen the residue, so you can wipe it away more easily. Bird droppings or other tough grime: pre-soak the area with a vinegar solution and allow it to soften before scrubbing with a damp microfiber cloth.
Looking in a mirror at 3:00 AM—often called the "witching hour"—is a popular superstition linked to the belief that the veil between the living and the spirit world is at its thinnest. Folklore warns that staring into a mirror in the dark risks seeing a warped reflection, inviting shadow entities into your space, or even allowing a mirror to temporarily trap your soul.
"Polishing the mirror" can refer to physical glass care, metalworking, or the classic Zen Buddhist metaphor for spiritual awakening. The context determines the ideal approach.

Rubbing alcohol (isopropyl alcohol) is an excellent, streak-free cleaner for standard household mirrors, and experts commonly recommend it. However, applying it improperly—or using it on specialized/first-surface mirrors—can cause permanent damage.
